Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT96WE26SN is determined by strict equivalence across the following critical parameters:

Connector Architecture: 26-position configuration with female socket termination and plug orientation Mechanical Compatibility: Shell size E (17-26 insert) with threaded fastening and free-hanging mounting Electrical Performance: 7.5A current rating with gold-plated mating contacts (50.0µin thickness) Environmental Specification: Shielded construction, composite shell with olive drab cadmium finish, operating range -65°C to 175°C Termination Method: Crimp-style contact attachment Regulatory Compliance: EAR99 export classification, HTSUS code 8536.69.4020, MSL 1 rating

The substitute part D38999/26FE26SN from Glenair meets these parameters within the MIL-DTL-38999 circular connector family. Substitution is valid only when all listed parameters align with system requirements.

Parameter Comparison

Engineering Selection Recommendations

The D38999/26FE26SN from Glenair is a direct functional equivalent to the discontinued ACT96WE26SN. Both connectors conform to MIL-DTL-38999 specifications and share identical electrical, mechanical, and environmental parameters.

Product Status Consideration: The ACT96WE26SN is discontinued at DiGi Electronics, while the D38999/26FE26SN maintains active product status with current manufacturing support. Selection of the Glenair substitute ensures continued availability and supply chain continuity.

Compliance Alignment: Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications, supporting equivalent regulatory treatment in procurement and export documentation.

Inventory Position: Both parts maintain adequate stock levels (1114 units and 1135 units respectively), supporting immediate procurement requirements.

The substitution is valid for all applications requiring a 26-position MIL-DTL-38999 Series III circular connector plug with female sockets, crimp termination, and the specified environmental and electrical ratings.

Frequently Asked Questions (FAQ)

Q: Can the D38999/26FE26SN directly replace the ACT96WE26SN in existing assemblies?

A: Yes. Both connectors share identical specifications across all critical parameters: 26-position configuration, female socket termination, shell size E, crimp termination, threaded fastening, shielded construction, gold contact finish, and operating temperature range. Mechanical and electrical compatibility is maintained.

Q: What is the significance of the MIL-DTL-38999 Series III designation?

A: MIL-DTL-38999 Series III is the military specification governing circular connector design and performance. Both the ACT96WE26SN and D38999/26FE26SN conform to this standard, ensuring interchangeability within systems designed to this specification.

Q: Are there differences in packaging between these parts?

A: The ACT96WE26SN is listed with unspecified packaging, while the D38999/26FE26SN is supplied in bulk packaging. Packaging differences do not affect connector functionality or compatibility; they relate only to order quantity and handling procedures.

Q: How do the contact finish specifications compare?

A: Both connectors feature gold-plated mating contacts with 50.0µin (1.27µm) thickness. This specification ensures equivalent electrical performance and corrosion resistance in aerospace and military environments.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture sensitivity concerns. Both parts carry this rating, eliminating moisture-related storage or handling restrictions during inventory management.

Q: Are export restrictions identical for both parts?

A: Yes. Both connectors carry EAR99 export classification and identical HTSUS codes (8536.69.4020), supporting equivalent treatment in export compliance documentation and procurement processes.

Q: Why is the ACT96WE26SN discontinued while the D38999/26FE26SN remains active?

A: Product discontinuation decisions reflect manufacturer supply chain strategies and market demand. The Glenair D38999/26FE26SN maintains active status, providing continued manufacturing support and availability for new and replacement applications.
